DOCUMENT-FILING CASE Application filed August 29, 1907. Serial No. 390,572.

as usedtor filing documents and other papers.

' The object ofthc invention is to provide mechanism for locking the filing drawers or bases so that they cannot be opened by an unauthorized person, which mechanism is cos of operation so that very large units can be ooked and unlocked simultaneously with little effort, and whichfurthermore, is so con structed that a filing base or drawer can be put in and automatically locked w hen the remaining filing bases are locked and Without the use of springs in the mechanism.

The invention comprises the construction.

and arrangement of parts hereinafter described and claimed.

In the accompa "rig drawings Figure l is a horizontal sectl' i thrcugl'i a portion of a filing cabinet constructed. according to our invention; Fig. 2 is a vertical section therethrough taken from front to rear on the line 2--2 Fig. 1; Fig. 8 is a similar section taken from side to side on the line 33 Fig. 1; Fig. 4 is an enlarged view of a portion of F 2, partly broken away; Fig. 5 is an enlarged view of thekey locking means shown in Fig. 2; Fig. 6 is a longitudinal section through. the o crating lever; and Fig. 7 is a cross section t ough the same.-

The cabinet comprises a suitable casing having top, bottom, s de and rear walls, the drawin s showing the side walls 1 and the rear W51 2, but do not show the top and bottom. The cabinet is divided. by horizontal partitions 3 and vertical partitions l forming a series of pockets or pigeon holes for the reception of the filing bases 5, which may be either in the form of a drawer or a modified base having a bottom. 6 and front-7 provided with suitable means for-holding the docu ments to be filed, such holding means not being shown.

The locking mechanism shown comprises rock shafts Sfone for each tier of filing bases Specification of Letters Patent.

erably is made telescoping so that it can be drawn outto get a long leverage for operating the locking device and when not-1n use i can be pushed inwardly so as not to project far beyond the casing. As shown the lever comprises the outer operating bar 25 and the inner substantially tubular art 26 into which the bar slides, said bar being held from accidental disengagement by being providedwith aslot 27 through which the pivot pin 24 projects. The tubu ar portion 26 at its inner end carries apart 28 wbich has connection with the bell crank'lever 19. The outer end of the tubular section 26 is rovided with a tongue 29 which engages an is guided by a rod 30 secured to the casing.

The lever 23 may be arranged to be locked so that it cannot be operated by an unauthorized'person, by any suitable keylocking means, such as a key lock 31 mounted on the frontof one of the filing bases, and so positioned that its bolt 32 holds the lever in the osition which it assumes when all of the filing bases are locked. When said bolt is withdrawn the lever can be swung to the opposite position to raise the vertical bar '17 and through the same rotate the several rock shafts 8 to disc age the.hooks 9 from the rear ends of the bases.

The operation of t e a paratus described will be understood ,from t. e illustration and description. The specific mechanism s own and described can be varied within considerable limits. For instance, a sliding operating member could be substituted for the pivoted operating lever. Also- -difierent. mechanism might be used in place of the bell crank lever for transferring the motion from the lever to the upright bar. The shape of the locking hooks or members The locking mechanism described is so constructed that a filing base can be pushed in and automatically locked when the other filing bases are locked and without disturbing the latter, this being eil'ected by the lost motion connection between the hook and rock shaft and without the necessity of s rings or other easily derangeable member. he locking movement is practically a .rotary one so that friction is eliminated to such an extent that the mechanism can be applied to sections of very large size and scares ing member arran ed to be drawn out through the front 0 the casing, and'a keycontrolled lock arranged to engage said lever to prevent its actuat1on.
